' '1 Claims. (01. 242-130) The invention relates to adjustable supports and more particularly to a spool skewer which is adiustablefor insertion into the bores 01 spools or the like of diflerent diameters.

One object of the invention is to provide a spool skewer or yarn package support which may be easily and quickly manipulated ,to set it for insertion into spool bores of any one of a plu- Y ralitycof different diameters.

Another object of the invention is to provide an adjustable support of the general type indicated which is simple and cheap to make, although rugged and strong in construction.

Further objects and advantages of the invention will become apparent as the following description proceeds, taken in connection with the accompanying drawing in which:

Figure l is a perspective view of an adjustable spool skewer embodying the invention.

Fig. 2 is a rear elevation of the device of Fig. 1.

Fig. 3 is a front elevation of the device of Fig. 1 with a yarn package spool of large interior diameter supported thereon.

Figs. 4 and 5 are respectively a front elevation and side elevation of the device of Fig. 1 with a yarn package sleeve and spool thereon having a bore of small diameter, Fig. 5 being partially in section.

The invention has been shown herein as embodied in a skewer or support for yarn packages such as are used in creels for high speed warpers. It will be understood, however, that the skewer herein contemplated is also adapted for other uses and for supporting spools or the like in other as in Figs. 1 and 3 so as to accommodate a yarn sleeve having a relatively large interior diameter or the support may alternatively be adjusted with the prongs spaced more closely together as shown in Figs. 4 and 5 to accommodate a smaller diameter sleeve l4}. Packages or cheeses of yarn li are wound on such sleeves in a suitable winding machine, for example, and then these packages of yarns are placed in creels and the yarn transferred to a warper beam. For various reasons it is sometimes necessary to use different sizes of spools or sleeves, the smaller size being preferred when the package of yarn is to be dyed after spooling and before being wound on the warper beam. Since the creeling time," that is, the interval required for placing fresh yarn packages on the creel represents idle time for expensive associated machinery it is requisite that such factors as a diflerent size of yarn package spool or sleeve should interfere as little as possible with the setting up of the creel. Accordingly a quickly adjustable yarn holder support is highly desirable.

The prongs Ii and I2 of the skewer have been shown herein as projecting arms on a corresponding pair of opposed L-shaped brackets, which, for the'sake of economy are preferably fashioned as stampings from sheet metal. The lower bracket, designated generally by the numeral I! (Fig. 1) includes, in addition to the prong arm ii, an angularly disposed base arm I6. This base arm is bolted to the base of supporting bar It) (Fig. 5) with a spacer collar l'l interposed between the abutting faces of the bracket and types of machines. Although a particular embase bar. Similarly, the upper bracket, desig bodiment of the invention has been shown and nated generally by the numeral I 8, also includes, described in some detail in order to make clear in addition to itsprong arm 12, an angularly disthe practice of the invention, there is no intenposed base arm i9 which is arranged to lie against tion to thereby limit the invention to such emthe face of the base bar [0. In the case of the bodiment, but, on the other hand, the appended 40 upper bracket, however, it is vertically adjustable claims are intended tocover all modifications and on the base I0, rather than being rigidly fixed alternative constructions within the spirit and thereon as in the case of the lower bracket l5. scope of the invention. For this purpose the base arm IS, on the upper In the particular construction shown (Fig. 1) bracket I8, is given a fork shape, being slotted the support embodies a channel shaped metal at 20 (Fig. 1) with the arms of the fork straddling base or bar ill from which a pair of'prongs II the spacer collar l1 (Fig. 2). In this way the and II project in generally parallel spaced relaspacer collar serves to guide the upper bracket tionship. These prongs are inserted into the in its adjustable movement and prevents lateral interior axial bore within a yarn package spool displacement of the lower end 'of the bracket or sleeve I (Fig. 3). By adjustment of the arm 19. spacing between the prongs il-l2, through the To hold the upper bracket prong 12 in either medium of an improved construction herein deof two selected positions of adjustment, with rescribed, the support is adjusted to accommodate spect to the lower prong II, a pin and slot conspools of different interior diameters. For exnection is formed between the upper bracket and ample, it may be adjusted with the prongs spaced the base bar Iii. For this purpose a curved slot M (Fig. 2) is fashioned in the base bar it and is provided with laterally ofi'set pockets or sockets 2! at its opposite ends. In this slot rides a projection on the upper bracket id, shown herein as a pin 22 riveted to the base arm of the bracket (Fig. and having an enlargement 22 thereon which bears against the inner face of the base bar it to prevent the bracket it from pulling away from the base bar. The pockets 2W are disposed in longitudinal alinement with the spacer collar Ill on the base bar It so that when the pin 22 is in one or the other of the pockets 2| the upper prong arm l2 will be disposed in its corresponding upper and lower positions shown respectively in Figs. 1 and 5. A helical tension spring 23, anchored at its opposite ends to the base bar it and to the pin 22, yieldably urges the pin into one or the other of the pockets 2 i so that it is firmly seated therein.

As a means of securing the yarn sleeves M or M on the skewer prongs li-i2 leaf springs 26 and are provided (Figs. 1 and 5). These leaf springs are bolted to the inner sides of the respective prong arms and are provided with rounded abutments 2d and 25 at their outer ends which project through complemental apertures of the prongs so as to engage frictionally the interior surfaces of the sleeves, which are telescoped over the prongs. The ends of the prongs are bent or curved inwardly toward each other (Fig. 5) to facilitate their insertion into the sleeve.

In the operation of the device, if it is desired to support a large yarn package sleeve such as the sleeve M (Fig. 3), the skewer is adjusted with the prongs lll2 spaced wide apart as shown in Fig. 1. To accomplish this adjustment the pin 22 is placed in the upper slot pocket 21! and is held firmly in such position by the tension spring 23. To move the prongs M--fl2 closer together so as to accommodate a smaller sleeve such as the sleeve It the operator grips the upper bracket it and pulls it upward and to the right (as viewed in Fig; 1) so as to free the pin 22 from the pocket Ell and permit it to slide freely down the slot 2 l. After the pin 22 has been pushed down the slot if it is seated in the lower pocket 2i by the spring 23, During this movement of the upper bracket 08 the lower end of its arm i9 is guided by the spacer collar ll which it straddles, so that at the completion of the movement the prong i2 is properly alined in closely spaced relation with the lower prong M. It is thus apparent that a strong and rugged skewer construction has been provided which can be quickly and accurately manipulated to accommodate yarn sleeves of different sizes.
